The City of Marietta has issued a boil advisory for water customers on Fourth Street from Montgomery to Ferguson Street, where water has been shut off for a water valve repair.

Customers in those areas who may have experienced a loss of water service or pressure are advised to rapid boil drinking water or water used in food preparation for two minutes following restoration of water service. The announcement says customers should flush their service lines using cold water lines only until the water is clear. Brown or cloudy water due to mineral deposits or air are normal discolorations after an interruption in service.

The water department estimates 30-35 customers are affected.

The advisory will remain in effect until customers are notified of its cancellation through local media.
